摘要： In an optical disc drive, a degradation of traveling performance of an optical pickup under hard acceleration or hard deceleration in a random access operation or the like results in a degradation of recording/reproducing performance. Groove structure is provided between two gears of a guide feed provided in an optical pickup, and the groove forms bending structure. Thus, the engagement state between a screw gear and the gears of the guide feed is stabilized. This makes it possible to prevent tooth jumping and step-out from occurring in the gears during the traveling of the optical pickup, achieving stable traveling. In consequence, the recoding/reproducing performance of the optical disc drive can be improved.

摘要： From an optical disc drive, internal static electricity has to be discharged to the outside to prevent breakage of electric components such as laser diodes. A grounding spring has been used to discharge static electricity from a unit mechanism to the enclosure of the optical disc drive but it is necessary to improve the reliability of the drive in consideration of the dimensional accuracy and workability of the spring. Thus the free end of a grounding spring having a cantilever structure is shaped like an arc and an end of the grounding spring has a curved structure. This configuration improves the dimensional accuracy and workability of the spring, so that the performance of the optical disc drive can be more reliable.

摘要： A metal pin is inserted into a hole cylindrically formed in a camera casing so as to be in contact with a shape-memory actuator. The metal pin and the shape-memory actuator are fixed by pressurization. The metal pin is further bonded to a printed circuit board via a solder to electrically and thermally contact the shape-memory actuator and the printed circuit board so as to form the camera module by reducing the wiring size and improving the cooling efficiency.
